Siemens 6ES7522-1BH10-0AA0 SIMATIC S7-1500 DQ 16x24VDC/0.5A BA PLC I/O Module

The Siemens 6ES7522-1BH10-0AA0 is a SIMATIC S7-1500 digital output module with 16 transistor outputs rated 24 V DC at 0.5 A each, grouped 8 per group at 4 A. It supports safety-oriented shutdown of standard load groups up to SIL2 per IEC 62061 and Category 3/PL d per ISO 13849-1, and ships with push-in front connectors.

Selection Notes

The 4 A per-group limit across 8 channels, not the 0.5 A per-channel rating, is what sizes this module for real loads - if all 8 channels in a group run near 0.5 A simultaneously, the group hits its 4 A ceiling and needs splitting across groups. The SIL2/Category 3 PL d safety-shutdown capability lets a standard F-CPU disable this module's output groups as part of a safety function, avoiding a separate fail-safe output module where only shutdown (not fail-safe diagnostics on the standard channels) is required. Choose this BA (basic) variant over a high-feature variant when 16 standard outputs with group-level safety shutdown is enough and per-channel diagnostics are not needed.

Applications

Standard digital output expansion for SIMATIC S7-1500 stations that also need a hardwired or software-triggered safe shutdown of load groups, such as machine sections requiring SIL2/PL d disconnection without a full fail-safe I/O module.
